A large solid cube is assembled by gluing together identical unpainted small cubic blocks. All six faces of the large cube are then painted red. If exactly 27 of the small cubic blocks that make up the large cube have no paint on them, how many small cubic blocks make up the large cube?

Yes, this is a very valuable suggestion...follow-up questions are fine within the same topic, but when you tag an unrelated question to an existing topic, it can make a topic convoluted and hard to follow.

if 27 cubes have no face painted then have the next bigger cube made be gluing small cubes on each face to complete the cube. Since the bigger cube is made of smaller cubes it should have 64 small cubes. Because 3 cube is 27 and 4 cube is 64. Now you can proceed further
